A college student Tree Gelbman relives the day of her murder with both its unexceptional details and terrifying end until she discovers her killer’s identity. Tree is a blissfully self-centered co-ed whose world revolves around just one person. When she hazily wakes up on the morning of her birthday in the bed of supposed one-night stand Carter, she soon discovers that today is anything but ordinary. Stumbling back to her sorority—and into the expected judgment of roommate Lori and house president Danielle, Tree rushes through the routine of an average student. But as she experiences everything from the typical activists on the quad to her office-hours fling with professor Gregory, she can’t help but feel that she has seen and lived this day before.
